Performance artist Marina Abramović kicked off her latest work, “512 Hours,” at the Serpentine in London this week. Known for such engaging works such as “The Artist Is Present,” a 2010 Museum of Modern Art retrospective, Abramović will perform from 10 a.m. to 6 p.m., six days a week until August 25, for a total of 512 hours.

While the Serpentine is expecting long lines during this free exhibition (they recommend bringing water, sunscreen and umbrella), people from around the world will be able to view Abramović’s daily diary of her performance on www.illy.com starting at midnight Eastern Daylight Time tonight.

In “The Artist is Present,” museum visitors were invited to sit across from Abramović and gaze into her eyes for an unspecified amount of time. In “512 Hours,” visitors are instructed to enter the space without cellphones, cameras or recording devices. “They arrive into the space with nothing,” she said. “And from this nothing, something may or may not happen.” Abramović calls the work a journey and an experiment. “I can succeed or I can fail,” she said. “Let’s see what will happen.”

The artist will upload videos, and give a rundown on the day’s developments and variations.
